Y

The fuel thus produced may be substituted for ordinary soft or bituminous coal for forgework or in furnaces of all kinds and is also adaptable for use in heating or cooking stoves of the ordinary construction. It is exceedingly inflammable, and the fire may be started with ordinary kindling-wood. Under combustion it is free from all gases, burns freely With these and other objects in view, as'
